Application filed-March 24,1909. Serial No. 485,481.

of New Kensington, county of Westmore-.

land, State of Pennsylvania, have invented a new and useful Improvement in Metal Carlines, of which the following is a specification'.

My invention relates to metal carlines and has for its principal objects to provide for the manufacture of carlines of malleable iron'; to facilitate the repairthereofby making it of interchangeable parts; to conform the carline to roofs of various pitches,- to

cars of various widths, .and to ridge poles of VaI'musdImensrOns; and toosecu're other advantages hereinafter appearing.

. The invention consists principally in mak ing the car-line of, two body member s-- of malleable-iron and an interme'dla'te connectln'g member.

pitch ofrthe carline. 4

It also consists'in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

In 1 the accompanying drawing, which forms part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure l is" a transverse section through a portion of a car roof showing a metal carline'embodying myinvention; Fig. 2 is a fragmentary transverse section showing a modification of the key member; Fig. 3 is a transverse section through a car roof showing a modification of the body member of the carline; Fig. 4 is a fragmentary. view showing a further modification of the key member; Fig.v 5 is an'enlarged fragmentary view illustrating the manner of connecting the body members to the key member; Fig. 6 is a top plan view of vthe portions shown in Fig. 5; Fig. 7 is a section on the line 77 of Fig. 5; Fig. 8 is a section on the line 8--8 of Fig. 5;.Fig. 9 is a section on the line 99 of Fig. 5; Fig. 10 is a fragmentary view partly in elevation and partly in section showing a modification of the body members and key member; Fig. 11 is a top plan'view of the further modification of the body members and key member.

The cal-line illustrated in the accom anying drawing-comprises two body mem ers 1 and an interm'pdiate'key or connecting memher 2. The-body members are of any suitable cross section; but in order-to adapt them for manufacture by casting malleable iron, they are preferablymade of I-section, wherein the metal is of substantially the same.'thickness at all points in the section. "Each body. member preferably tapers or-inclines toward its outer end, where it is provided with parallel downturned flanges 3, 4 integral therewith and adapted to straddle i the side plate of the car; In order to reinforce these downturned flanges, they may be connected by a vertical web 6 provided therefor on the underside of the end of the carline, as illustrated in Fig. 3. Preferably,

these body. members are provided with up It also consistsin making the parts--sepfawardly. extending flanges 6, 7 on top thereof which' are arranged'transversely in pairs to form seats for purlins 8, or arranged longitudinally along the margins to form seats for wooden nailing strips 9.

a The inner endof each body member is key or connecting member. This key member is preferably made in the form of a blunt wedge block whose narrower'end'is lowermost-.1 Inclined slots 10 are formed in the sides of the wedge block adjacent to the inclinededges of said key member or wedge block, whereby the marginal portions of said key constitute undercut. lugs .or headed tongues 11. The lower portion, of the inner end of each of the body members is thickened and in the edge of each side face thereof is formed a T-slot or groove 12 which is the counterpart of the headed tongue of the wedge block. The top of the key or wedge block is provided at its ends with upwardly .with'sockets adjacent to said lugs. The top of the inner end of each body member is provided with a projecting strap 14 lutegral therewith. At its point of attachment to the body, this strap projects upwardly substantially horizontally, to make it fit over the lug and have its end countersunk in the adjacent socket of the key.

adapted to interlockwith the intervening extending lugs 13 integral therewith and and thence is rebent downwardly and thence In assembling the parts, the headed tongue V of the key is centered below the T-jslot or v groove 12 of the body member, and'the'two members are caused to interlock by sliding the tongue into the groove until the top of the lug on the key comes in-contact'with the top-of the groove in the rebent strap. The body members and the key member thusassembled hold-together without the use of bolts, and consequently, they maybe disengaged whenever requ red. For instance, a broken member of the carline may be re placed with a new member. It s noted, however, that .the ridge poles rest flush againstfthe top of the key member and that the bolts for securing. said ridge pole to its -'seat-extend through said. key member and the strap "thereon. v

vThe separabilityof themembers of the carline has the important advantage of adapting such members for use with roofs ofvariouspitches and with cars of various widths.' Forinstance, the lengthof the carline'maybe increased to a limited extent by to adjust the pitch of the carline.

the curvature of the body 'member.

replacing one key member or wedge block with another key member or wedge block of greater width. Ofcourse, thesame key member orj'wedge blockmay be used interchangeably with body members of various lengths, whereby the range ofad'justment is increased. So, too, the pitch'of the carline may be increased by replacing one key memher or wedge block with another whose sides have a greater inclination.

Fig. '12 illustrates a construction wherein the relation of the body member to a given key member or wedge block may be varied In this construction, the inner ends of the body members are curved in arcs whose centers are adjacent to the. outer ends of the carline, and the sides of the .key member or.

wedge block 15 are concaved to conform to As in the construction above described, the key member and the body members are provided.

withinterlocking tongues and grooves, wh ch, 1n thepresent instance, are disposed in circular arcs. By this arrangement, the

. -bodymembers and the key member are adapted to interlock throughout a consider-- able range of variation of 'tl1e pitcln The "members are locked together by any suitablemeans. For instance, the concave edges of the key member have transversely arranged teeth 16 thereon, and the end portions of the respective body members have transverse bolt holes slightly overlapping said teeth.- In these holes are withdrawable bolts 17 which have longitudinal ribs or ridges 18 adapted to interlock with the teeth. of the key member and 'therebysecure the 4 members of the carline together. In Fig. 12,

the left hand body member is shown of lower pitch than theright hand body member.

Theconst-ruction shown in Fig. 10 shows the key member serrated along its edges and locked by ridged bolts, as described with reference to Fig. 12.

Obviously, my device admits of considerable modification without departing from my invention, and therefore I do not wish to be limited to the specific construction shown and described.

What I claim as my invention and desire to secure by LettersPatent-is 1x A three-piece =malleable iron carline consisting of two body members and an intermediate connecting member removably interlocking therewith. I 2. A car'roof comprising a plurality of cast metal carlines adapted to support the superstructure,'each of said carlmes comprising two elongated, body members and an intermediate replaceable key member detachably secured tosaidbody members, the
